Chelated Magnesium

Interested in starting to take some magnesium, and heard chelated magnesium is the way to go for bioavailability. I went to whole foods and picked up a bottle of chelated magnesium, but now looking at the ingredients, it says it's 200mg of magnesium (as magnesium oxide and magnesium aspartate). Everything I'm reading online now says that magnesium oxide is not chelated magnesium. So, is "chelated" unrelated to the specific form of magnesium (i.e. you can have chelated magnesium oxide), or is the whole foods bottle just labeled incorrectly?

Right, so magnesium and its absorption can be classified as one of two things:
- It gets absorbed enough to prevent a deficiency, but fucked it if does anything else
- It gets absorbed nearly perfectly and can influence the brain in a depressive/protective manner
The latter category is Magnesium L-Threonate, everything else is the former category. Chelation does increase absorption, but in practical settings to avoid a deficiency it doesn't actually mean much.

Where is there conclusive evidence that L-threonate elevates brain magnesium levels more than glycinate? Also, theronetic acid is a much larger molecule than glycine, so the ratio of elemental magnesium to total pill weight is going to be much lower with L-threonate.
I have tried many different forms of magnesium, and found fully chelated magnesium glycinate to be just as effective as anything else, and for a much lower price. Also, there was a human study on L-threonate that should have already concluded by now. It was run by the people that developed L-threonate. However, to date there have been no results released, and the company has gone quiet on the issue. They will not respond to emails regarding the study, and do not mention it anymore in publications. If this much more expensive form turned out to be more effective in humans, why are they not publishing the results?
